Miniature Rose Plant Named &#39;Poulty021&#39;

ABSTRACT

A new garden rose plant of the Miniature class which has abundant, orange blend flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Botanical designation: Rosa hybrid.

Variety denomination: ‘Poulty021’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of roseplant which originated from a controlled crossing between the femaleseed parent, an unnamed seedling, and the male pollen parent, also anunnamed seedling. Both of the parent varieties are non-patented.

The two parents were crossed during the summer of 2009 and the resultingseeds were planted in a controlled environment in Fredensborg, Denmark.The new variety, named ‘Poulty021’, originated as a single seedling fromthe stated cross.

The new variety may be distinguished from its male pollen parent andfemale seed parent primarily by the following characteristics. Thefemale seed parent has orange red flowers while the new variety hasorange blend flowers. The male pollen parent has red flowers while thenew variety has orange red flowers.

The objective of the hybridization of this rose variety was to create anew and distinct variety with unique qualities, such as:

-   -   1. Uniform and abundant orange blend flowers;    -   2. Vigorous, but compact growth when propagated on its own        roots;    -   3. Exceptional disease resistance.

This combination of qualities is not present in previously availablecommercial cultivars of this type, known to the inventor, anddistinguish ‘Poulty021’ from all other varieties of which we are aware.

As part of the rose development program, Mogens N. Olesen germinated theseeds from the aforementioned hybridization during winter of 2009 andconducted evaluations on the resulting seedlings in a controlledenvironment in Fredensborg, Denmark. ‘Poulty021’ was selected in thespring of 2010 by the inventor as a single plant from the progeny of theaforementioned hybridization.

Asexual reproduction of ‘Poulty021’ by rooted cuttings was first done byMogens N. Olesen in the nursery in Fredensborg, Denmark in July, 2010.This initial and other subsequent asexual propagations conducted incontrolled environments have demonstrated that the characteristics of‘Poulty021’ are true to type and are transmitted from one generation tothe next.

DESCRIPTION OF THE DRAWING

The accompanying color illustration shows as true as is reasonablypossible to obtain in color photographs of this type, the typicalcharacteristics of the buds, flowers, leaves, and stems, of ‘Poulty021’.Specifically illustrated in the drawing are open flower viewed fromabove, flower petals detached, sepals detached showing receptacle andreproductive flower parts, leaves, and a flowering branch with manyunopened flower buds. Plants shown are 2 years of age.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulty021’,as observed in its growthin a field nursery in Marion County, Oreg. Observed plants are 2 yearsof age, and were grown on their own roots. Color references are madeusing The Royal Horticultural Society (London, England) Colour Chart,2001, except where common terms of color are used.

For a comparison, several physical characteristics of the rose variety‘Poulpar071’, U.S. Plant Pat. No. 24,549 are compared to ‘Poulty021’ inChart 1.
